Courtney's Creamy Growth Serum: Chapter 1

Chapter 1: Strawberry Shortcake

Courtney was a shy, short-haired blonde girl with pretty ocean blue eyes. She was on the shorter side standing at a meager 5'3, 106 lbs. She didn't have much cleavage or breasts to speak of barely able to fit into a B cup bra and to make matters worse, she was just turning 18. Impatiently awaiting puberty was an understatement, she was dying to be taller and bustier waiting for puberty to bring her the same overflowing 36DD breasts her long haired, blonde bombshell mother, Suzy, had flaunted at every occasion, in comparison was 5'9, 163 lbs.

She would spend hours in the mirror staring, touching, and massaging the flesh where her breasts should have been, her nipples like bullets, hard and sensitive. She spent a lot of time watching herself, imagining herself grow, filling out, her ass becoming a round, juicy peach. Her pussy would twitch and tingle every time she would daydream, getting wet, touching herself at the thought.

Today was the day things finally changed.

Courtney was spending a great deal of her time researching biochemistry, mostly hormonal studies, hoping one day to join a research team and develop a drug to speed up the puberty process in young girls who seem to be behind other, more developed, voluptuous girls. Her teacher; Professor Greg, had been proclaiming the other week about how he had synthesized a growth formula which had great results on the test animals he had brought into his lab to experiment the formula and dosages.

He had received a formal complaint and order to shutdown his lab after the FDA had discovered a rat the size of a small dog wandering the school grounds, supposed the rat had chewed through a section of the door and snuck into the cafeteria and began gorging on leftovers from the last school lunches. The formula had proved unstable after noticing the mouse had grown double its size on the first dosage alone, then increasing in size after consuming various foods.

Courtney waited all day through class painfully. She kept recalling this morning when her mom kept going on about her boyfriend's lack of responsibility and inability to please her, making inappropriate gestures towards her massive bust. Courtney, blushing red, turned her face away in embarrassment as Suzy continued on and then started jiggling her breasts trying to "show" Courtney how a woman needs to be handled properly.

Only a few more hours she thought, looking down at the chair, now slightly slippery from her dripping wet pussy, the waiting was torture and the more she thought about the formula the more she had trouble sitting still. Her mind raced, she thought "What would've happened if he gave that mouse two doses? three?" She squealed and whined quietly, a few of her classmates glanced at her, she quickly ducked her head, and waited for class to end.

She waited until sundown, hanging by an abandoned well far outside the school grounds, she had told Suzy, her mom, that she was staying late in an anime club. She snuck around the now dark school grounds, towards a building, with a restricted area sign, she ducked under the yellow caution tape and was outside the shutdown lab, searching for answers to her stunted growth.

The doors on the building were bolted shut, however a small wrecked section of wall along the left side of the structure seemed to be just small enough for Courtney to squeeze through, it may have been the only time her small size ever benefited her. The lab was small, compact, and a huge mess. Papers and broken glass were scattered across the hallways and floors. Courtney had worn her black combat boots she borrowed from her goth friend, Lynn, so she didn't feel too worried about it.

She tried her best to stay quiet, making her way to the chemical storage sector, most of the drugs were labelled, locked away or otherwise useless, but way in the back in a still somehow powered cooler. The cooler had a frozen note inside, along with 9 vials of a creme colored white liquid. The vials had exactly 1 ml of formula in each vial, properly cooled, and likely had active growth cultures. Courtney's eyes widened, her breath sped up and she started panting in excitement. She grabbed a cooler and realized it's fairly light and hastily made her way out of the lab and home.

She snuck in through the backdoor of her small suburb home and ran upstairs, quietly moving the dresser door and placing the cooler in the back of the closet. She closed the closet door, once again thankfully due to her small 5'3 frame and A-cup breasts she easily fit into the small walk-in closet. She flicked on a flashlight and removed the cover of the cooler, feeling a slight cool breeze hit her and she placed her now trembling fingers on the first vial, and the other hand on the note. The note read;

"CAUTION! GROWTH HORMONE TYPE: GGS (Giga-Growth Serum);

WARNING! Avoid excessive arousal, sexual activity, and food consumption while on GGS Possible side effects include; sexual arousal, hunger, euphoria, overconfidence. One 0.2 ml dosage in the morning with food, do not take more than the suggested dosage. No more than 1 ml per 48 hours.

"Fuck." Courtney thought as she read "in the morning with food...", how was she going to slip it by her mom. She shrugged and opened the first vial, the liquid looked like heavy cream and smelled of vanilla, her mouth began to water and she measured the vial loosely then took a sip. She checked how much she had taken, 0.1 ml, she took another swig, this time longer, letting more of the sweet creamy substance touch her soft lips as she sucked another 0.3 ml of the fluid trickle down her throat.

She flicked back the vial and took a look at how much she had taken, a double dosage of 0.4 ml! She licked her lips and started to feel warm, her thighs began to tingle, sending warm vibrations up her inner thigh into her pussy. She put down the vial and plunged her hand into her vagina, and began without a thought stroking it against the professor's recommendations.

A rush of fluid soaked her pussy through her now drenched panties, her other hand playing with her rigid nipples through her tank top. The feeling now spreading through her lower back and into her cute and small ass. She felt the rug underneath her slowly rubbing against her now swelling butt. Her ass began to grow, from a flat unnoticeable rear to a cute round apple bottom. This only fueled Courtney more, rubbing her soaking slippery pussy even faster, feeling the sensation grow even stronger.

That same warm feeling this time shot waves of euphoria and pleasure into her. She started to moan softly with each growing pulse witnessing her flat board of a chest at a 30A, rise and bud into 34B! Then another pulse, this time bigger shot her chest up to a 36C, her small nipples expanding and resonating with sensitivity.

The rug underneath her was sticky and damp, this entire time Courtney had been having multiple orgasms, her tongue crossing her now bigger and fuller lips frequently to stop from drooling from probably the most pleasure she had in her entire life. Another pulse shot through her, she felt her arms, legs, and torso tingle and stretch.

Slowly an inch a minute she rose from her 5'3, feeling her ass and breasts expanding against her now straining yoga pants, entirely soaking wet, and her tank top hearing an audible rip as she rose to 5'7 a whole four inches! She had been 5'3 and 103 lbs, she was standing tall at 5'7, and with the new larger breasts, ass, and thighs she had gained 34 lbs! She was now 137 lbs.
